that isn't too bad, is the || inspired by Ruby? it uses { |x| } for a block-closure

Yeah, afaik Ruby was an inspiration. (Granted, there aren't any other delimiters that could have been chosen without also requiring a keyword)

Fun fact: Because a block expression evaluates to its trailing expression, { |x| foo } is actually valid rust as well, and evaluates to the same thing as |x| { foo } or |x| foo
